Outline of Final Research Achievements

This study conducted the data acquisition of the attitude motions of whole balloon flight systems with the GPS loggers we developed. In 4-year-research term, 4 flight experiment were conducted, experiment data were successfully recovered from 3 experiment. The data recovery of the remaining 1 data set is still being processed.
This study first aimed to clarify the transient attitude behavior of the balloon flight system, However, during the process, we found that the ambient temperature around the logger seemed to affect strongly on the measurement data. Therefore, before studying the transient state, we studied the influence of the temperature on the attitude data, and efficient process to remove the influence in the post-process.

Academic Significance and Societal Importance of the Research Achievements

成層圏気球は宇宙科学分野において，一つの観測手段であるばかりでなく，最先端のテクノロジを宇宙に近い環境におけるミッションに適用し，人工衛星などの宇宙技術開発につなげるためにも重要なプラットフォームである．気球の利用目的には，機器を搭載するゴンドラを特定の方向に向ける制御が必要となるものもある．一方，方向制御システムを設計するためには，制御対象の特性をよく把握する必要がある．現在そのようなデータの蓄積はは十分ではない．本研究はデータ収集，蓄積という点だけでも，気球実験を通した宇宙技術開発に対して大きな貢献となると期待される．
